Embodiment Construction

[0040] figure 1 and 2 A motor vehicle steering wheel 1 with a detection device according to a preferred embodiment of the invention is shown. here from figure 1 and 2 Overview It can firstly be seen that in the embodiment shown, steering wheel 1 comprises two finger sensor devices 2 and 3 . In this case, finger sensor devices 2 and 3 are each arranged on the rear side of steering wheel 1 facing away from the driver in the transition region between steering wheel spokes 4 and the rear side of steering wheel main body or steering wheel cushioning part 5 .

[0041] It can be seen that the positioning of the sensor devices 2 , 3 allows the required measurement of vital parameters of the driver to be carried out with as little effort as possible, eg while driving, without having to take the hands off the steering wheel 1 . In this case, measurements can generally be carried out without changing the grip on the steering wheel 1 , since according to the invention the steering whe...

Abstract

The invention relates to a detection device for detecting at least one vital parameter of a person in a motor vehicle with a steering wheel (1). The detection device comprises a finger sensor device (2, 3) with an optical sensor device (8), the finger sensor device (2, 3) being arranged on the steering wheel (1) in the transition region between a steering wheel spoke (4) and the steering wheel body (5). In a preferred embodiment, the sensor surface area is formed by the actuation surface of a push-button switch. The push-button switch can, in particular, be a shifting paddle for a gearshift transmission. The sensor surface area can have an electrically conductive surface for generating an electrocardiogram (ECG).

Description

technical field [0001] The invention relates to a detection device for detecting at least one vital parameter of a person in a motor vehicle according to the preamble of claim 1 . Background technique [0002] The detection of vital parameters in humans by optical plethysmography (volume fluctuation measurement) and pulse oximetry (oxygen saturation measurement) is known per se and is usually performed by means of optical measurements of, inter alia, pulse rate, pulse rate variation and arterial oxygen saturation. This is achieved non-invasively by measuring the absorption or reflection of light as it passes through tissue. [0003] In principle, plethysmography and pulse oximetry are based on similar optical measurement methods. Whereas plethysmography is performed by means of optical measurements of light absorption changes produced by volume fluctuations in particular blood vessels, pulse oximetry is based on red and infrared measuring beams that are transmitted through ...
